If you follow the forum the Samsung servers might be having fits. Be sure to call Samsung to check if they are working and have them guide up through the first setup.
not sure if this is a common problem but hee goes;
I bought the above TV for the Kids and as it has a USB Port for a Samsung Wireless LAn Adapter I bought one this evening. I bought the WIS12ABGNX Adapter and its compatable with this TV and when I connected it to the TV I went through the steps and connected it to my WiFI. All good so far. But now, I am at a loss what I can actually do with it? I had thought I couod access some form of internet and maybe install Netflix for hte kids but I cant seem to do that, I can even update the TV's sofeware.
Any help would be much appreciated!
